summary
Adxl345 is a small and thin three-axis accelerometer with low power consumption, which can
The acceleration up to 16 g was measured with high resolution (13 bits). Number of digital outputs
According to 16 bit binary complement format,
It can be accessed through SPI (3-wire or 4-wire) or I2C digital interface.
Adxl345 is ideal for mobile device applications. It can be used in tilt detection applications
The static acceleration of gravity can be measured, and the dynamic acceleration caused by motion or impact can also be measured
Speed. It has a high resolution (4 mg / LSB) and can measure a tilt of about 0.25
Angular variation. No need to use adxl345 and other digital output accelerometers
A / D conversion can save system cost and circuit board area. In addition,
Adxl345 is a small and thin ultra-low power 3-axis accelerometer with resolution
High (13 bits), measuring range of 16g. Digital output data is 16 bit binary
The complement format can be accessed through SPI (3-wire or 4-wire) or I2C digital interface.
Adxl345 is ideal for mobile device applications. It can be used in tilt detection
It can also measure the motion caused by motion or impact
State acceleration. Its high resolution (3.9mg / LSB) can measure less than 1.0
Tilt angle change.
The device provides a variety of special detection functions. Active and inactive detection function communication
The acceleration on any axis is compared with the threshold value set by the user to detect whether there is operation
Movement occurs. The knock detection function can detect single vibration and double vibration in any direction
Made. The free fall detection function can detect whether the device is falling. these ones here
The function can be mapped independently to one of the two interrupt output pins. Applying
The patented integrated memory management system adopts a 32 level FIFO
(FIFO) buffer, which can be used to store data and load the host processor
Minimize and reduce overall system power consumption.
Low power mode supports intelligent power management based on motion, so as to achieve extremely low
Power consumption is measured by threshold and acceleration.
Adxl345 is made of 3 mm 5 mm 1 mm, 14 pin small ultra thin plastic
Encapsulation.
